Question

Quizplus · Accepted Answer

Peter's lack of social responsiveness, solitary behavior, repetitive movements, and insistence on sameness are all characteristic of autism. Childhood schizophrenia and avoidant disorder do not typically present with these specific symptoms, and while intellectual developmental disorder can sometimes be accompanied by social difficulties, it is not typically associated with the repetitive behaviors or insistence on sameness seen in autism.
